<td><strong>polymorphism</strong></td> <td>The ability of different objects to respond to the same function call in different ways.</td> <td>Core concept in object-oriented programming, especially with virtual functions.</td> </tr> <tr> <td><strong>inheritance</strong></td> <td>A mechanism where one class derives properties and behaviors from another.</td> <td>Used to create class hierarchies and reuse code.</td> </tr> <tr> <td><strong>encapsulation</strong></td> <td>Hiding internal details and exposing only necessary parts through interfaces.</td> <td>Helps protect data and maintain clean architecture.</td> </tr> <tr> <td><strong>constructor / destructor</strong></td> <td>Special functions that initialize and clean up objects.</td> <td>Used in C++ to manage object lifecycle.</td> </tr> <tr> <td><strong>reference / pointer</strong></td> <td>Ways to access or refer to memory locations.</td> <td>Essential in C++ for memory management and function arguments.</td> </tr> <tr> <td><strong>overload / override</strong></td> <td>Overload: same function name with different parameters; Override: redefine base class behavior.</td> <td>Used to extend or customize functionality.</td> </tr> <tr> <td><strong>compile-time / runtime</strong></td> <td>Compile-time: when code is translated to machine code; Runtime: when the program is executed.</td> <td>Important for debugging and performance analysis.</td> </tr> <tr> <td><strong>stack / heap</strong></td> <td>Two types of memory allocation: stack is fast and temporary, heap is dynamic and persistent.</td> <td>Used in variable storage and object creation.</td> </tr> <tr> <td><strong>thread-safe</strong></td> <td>Code that can safely run in multi-threaded environments without causing errors.</td> <td>Crucial in concurrent programming.</td> </tr> <tr> <td><strong>undefined behavior</strong></td> <td>Code that may produce unpredictable results due to language rules violations.</td> <td>Should be avoided to ensure stability and portability.</td> </tr> <tr> <td><strong>template / generic</strong></td> <td>Code structures that work with any data type.</td> <td>Used in C++ (templates) and TypeScript (generics) for reusable components.</td> </tr> <tr> <td><strong>STL (Standard Template Library)</strong></td> <td>A collection of pre-built classes and functions for common data structures and algorithms.</td> <td>Widely used in C++ for vectors, maps, sets, etc.</td> </tr> <tr> <td><strong>lambda expression</strong></td> <td>A concise way to define anonymous functions.</td> <td>Used in functional-style programming and callbacks.</td> </tr> <tr> <td><strong>scope / lifetime</strong></td> <td>Scope: where a variable is accessible; Lifetime: how long it exists in memory.</td> <td>Important for managing resources and avoiding bugs.</td> </tr> </tbody> </table> <h2 id="industry-expressions-for-game--it-developers">Industry Expressions for Game &amp; IT Developers </h2><table> <thead> <tr> <th>Expression</th> <th>Meaning</th> <th>Usage Scenario</th> </tr> </thead> <tbody> <tr> <td><strong>MVP (Minimum Viable Product)</strong></td> <td>The simplest version of a product that still delivers value.</td> <td>Used during early product development to test core features quickly.</td> </tr> <tr> <td><strong>pivot</strong></td> <td>A major change in strategy or direction.</td> <td>When a product or business shifts focus due to feedback or market changes.</td> </tr> <tr> <td><strong>iteration</strong></td> <td>One cycle of development and improvement.</td>

ads, in-app purchases, subscriptions, etc.</td> </tr> <tr> <td><strong>sandbox environment</strong></td> <td>A safe, isolated testing space.</td> <td>Used for experimentation without affecting production systems.</td> </tr> <tr> <td><strong>scalability</strong></td> <td>The ability of a system to handle growth.</td> <td>Important for systems expected to serve many users or large data loads.</td> </tr> <tr> <td><strong>CI/CD (Continuous Integration / Deployment)</strong></td> <td>Automated processes for building, testing, and releasing code.</td> <td>Core to modern DevOps workflows
